SHOCK-LOADER.

Patented Deo. 14, 1909.

Application filed May 22, 1906, Serial No. 318,165. Renewed February 8,1908. Serial No. 414,982.

To all whom it may concern:

Be it known that I, JAMES B. SCHUMAN, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented certain new and useful Improvements in Shock-Loaders, ofwhich the following is a specification.

The object of my invention is to produce a rack for the convenientlifting of shocks of material, such as corn stalks, from the ground ontoa vehicle and arranging the same thereon so that they may be easilytransferred from the field, the construction being such that the loadingand unloading may be effected from either side of the vehicle.

The accompanying drawings illustrate my invention.

Figure 1 is a perspective view of the vehicle showing the manner of itsuse; Fig. 2 is a rear end elevation, and Fig. 3 a` detail of theadjustable support for the lifting cable.

In the drawings, 10 indicates a suitable running gear, preferably a`standard farm wagon, upon which is laid a platform 11. This platform isprovided at each end with a firmly braced post 12 and ends 13. Pivotedto each post 12 near its lower end is a standard 14, and the upper endsof these standards are connected by a bar 15, thus forming an inverted U-shaped structure which may be swung to either side of the vertical, theamount of movement being limited by guards 16, one of which embraces,

cach of the standards 14. The U-shaped structure is firmly braced, andmounted upon its bar 15 is a carriage 17 to which one end of the liftingcable 18 is attached. Carriage 17 carries a pulley block 19 throughwhich the cable 1S passes, said cable passing from thence over an idler20 supported at the upper end of the rear standard 14, and from thencethrough a pulley block 21 attached to the lower end of the rear post 12,the free end of the cable being' arranged to attach to the harness of asuitable draft animal, as shown.

The platform 11 is provided at each corner with a. depending bracket 2V,and these brackets are connected in longitudinal pairs by a U-shapedguide 2G which normally lies in a substantially horizontal planeprojecting outward from the platform, being held in this position byflexible supports 27.

The height of the structure 26 is substantially equal to the distance atwhich the pivotal point of the structure is placed below the platform11, so that, when the structure 2G is swung upward, its base will liesubstantially even with the top of the platform. Each end 13 is providedwith two sets of hooks or hangers 28 adapted to receive and support thedetachable side bars 29.

The operation is as follows: The parts are assembled, as shown in Fig.1, and the structure 14-15 inclined away from the open side of thevehicle. A suitable shock grapple 30 is then placed about a shock 31 andthe lifting cable 1S attached thereto. As the cable is pulled the shockwill be first drawn over against the adjacent U-shaped guide 2G, and, asthe shock is lifted, said guide will swing upward therewith so as toassist in the delivery of the shock to the platform. The downward pullupon the cable between pulleys 2O and 21 serves to hold the structure14-15 in position. The shocks which are lifted first are packed tightlyagainst the siderails 29, and carriage 17 is shifted along the bar 15 tobring the carriage opposite the point at which the next shock is to bedeposited, said carriage being held in position by means of a pawl 17entering notches 15 formed in the lower side of the bar 15.

I claim as my invention:

1. The combination of a portable platform, a swinging structure mountedthereon to swing on a substantially horizontal aX'is and consisting inpart of a longitudinal beam, means for holding said structure uponeither side of the vertical, and lifting mechanism supported on saidbeam and having lifting action independent of the movement of the saidswinging structure.

2. The combination of a portable platform, a substantially invertedU-shaped structure, means for supporting said structure on the platformwith the longitudinal beam thereof upon either side of a medial line ofthe platform, and lifting mechanism supported on said longitudinal beam.

3. The combination of a portable platform, a swinging structure mountedthereon to swing on a substantially horizontall axis and consisting inpart of a longitudinal beam, means for holding said structure uponeither side of the vertical, lifting mechanism supported on said beamand having lifting action independent of the movement of the saidswinging structure, end walls arranged at each end of the platform,detachable side rails, and means for supporting said rails at eitherside of the vehicle.

4c. The combination of a portable platform, a substantially invertedU-shaped structure, means for supporting said structure on the platformwith the longitudinal beam thereof upon either side of a medial line ofthe platform, lifting mechanism supported on said longitudinal beam, endwalls arranged at each end of the platform, detachable side rails, andmeans for supporting said rails at either side of the vehicle.

5. The combination of a portable platform, a swinging structure mountedthereon to swing on a substantially horizontal axis and consisting inpart of a longitudinal beam, means for holding said structure uponeither side of the vertical, lifting mechanism supported on said beam,and guide rails arranged at each side of the platform below the levelthereof and pivotally supported to project from the platform.

G. The combination of a portable platform, a substantially invertedU-shaped structure, means for supporting said structure on the platformwith the longitudinal beam thereof upon either side of a medial line ofthe platform, lifting mechanism supported on said longitudinal beam, andguide rails arranged at each side of the platform below the levelthereof and pivotally supported to project from the platform.

7. The combination of a portable platform, a swinging structure mountedthereon to swing on a substantially horizontal axis and consisting inpart of a longitudinal beam, means for holding said structure uponeither side of the vertical, lifting mechanism supported on said beam,end walls arranged at each end of the platform, detachable side rails,means for supporting said rails at either side of the vehicle, and guiderails arranged at each side of the platform below the level thereof andpivotally supported to project from the platform.

S. The combination of a portable platform, a substantially invertedU-shaped structure, means for supporting said structure on the platformwith the longitudinal beam thereof upon either side of a medial line ofthe platform, lifting mechanism supported on said longitudinal beam, endwalls arranged at each end of the platform, detachable side rails, meansfor supporting said rails at either side of the vehicle, and
